Abstract: Embodiments of the present application provide a method and an apparatus for compressing a label stack. The method includes: obtaining a first label stack corresponding to a forwarding path, where the first label stack comprises node labels corresponding to each node on the forwarding path; selecting a first node label from the first label stack, where when forwarding a packet, a node corresponding to the first node label is capable of encapsulating at least two layers of labels in the packet; replacing at least two adjacent labels located after the first node label in the first label stack with a first compression label, to generate a second label stack; and instructing a source node on the forwarding path to perform packet processing according to the second label stack. In this way, a length of a label stack pushed into the packet can be shortened.

Abstract: The embodiments of the present invention relate to the field of computer networks, and disclose a method and an apparatus for processing a multicast packet. The method includes receiving a multicast packet, acquiring a local router interface corresponding to the multicast packet according to a multicast routing entry carried in the multicast packet, and forwarding the multicast packet through the acquired local router interface to a clustered routing system interface for further transfer. The embodiments of the present invention can cluster several routing devices into a virtual routing system which externally acts as a single routing node for supporting a multicast service, so as to implement the efficient and reliable forwarding of the multicast packet in a clustered routing system with virtual aggregation, and enable the clustered routing system to support the multicast service with high efficiency and quality.
